Specification of Letters Patent.

Patented Aug'. 22, 1916.

-' Application filed March 7, 1916. Serial No. 82,738.

To all whom it may concern:

Be it known that I, GEORGE A. LUCKE,

- a citizen ofthe United States, residing at atory fixtures.

The primary object of the invention is the provisionof a stopper of this character wherein the construction thereof is novel in form so that it may be conveniently ap-* plied to the waste opening in a bath tub, wash basin or the like with despatch, and will serve to close the said opening Without the use of the ordinary rubber stopper or the like and-thereby dispensing with the chain connected with such stoppers.

7 Another object of the invention is the provision ofa stopper of this character which is inthe form of ashutter and is de,

signed to close the waste opening in the wash bowl or basin, the shutter being readily adjustable'by-hand so that the opening can be closed and opened at will.

A further object of the invention is the provision of a stopper of this character wherein the parts are assembled in a novel and unique manner so as to assure the positive closing of'the waste port or opening features of construction, combination of ele-. ments and arrangement of parts which will.

without possibility of leakage, the stopper being made from a minimum number of,

parts, and'can bereadily attached and detached from the waste port or opening. A still further object of the invention is the provision of a stopper ofthis character wherein wear thereon is reduced to a niinimum and the possibility of the stopper becoming defective is eliminated.

A still further object of the invention is the provision of a stopper of this character which is extremely simple in construction,

thoroughly reliable in operation, strong, du-

rable and inexpensive of manufacture.

Other objects will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the be exemplified in theconstruction hereinafi ter described, and the scope of the application of which will be defined in the appended claim.

In the accompanying drawings: Figure 1 is a top plan view of a stopper constructed in accordance with the invention; Fig. 2 is a fragmentary vertical sectional 'view through a bath tub at the waste port oropening therein showing a stopper applied; .Flg. 3 is a perspective view of the shutter;

Fig. 4 isa. perspective view of theattaching member, one part thereof being partly broken away; Fig. 5' is a perspective view of the base ring or collar.

'has arranged within the'same the usual guard C which is formed with-the crossed arm spider D, as usual, and into this guard is adapted to be inserted the ordinary. re-

silient -or other stopper which,.in the use of the present invention, isdispensed with as well as the chain carrying the same. It is of course understood that the portion of the bath tub is shown merely to illustrate the application and manner of useof the stop-j per hereinafter fully described, as said stopper is designed for use in wash basins or, other like lavatory fixtures.

I The stopper comprisesa base ring or col lar 10 which is of the required size to snugly fit within the guard C permanently mounted within the waste/opening or port. The ring or collar 10 is formed with an annular flange 11 which is outturned therefrom to be dis posed concentrically of the opening or port and has engaged with the outer edge thereof the clenched rim 12 of a c'onvexed or semispherical shaped capor shell 13 so that it forms a permanent part ofthe ringor collar 10 and is provided centrally thereof with an aperture 14' while concentrically of the latter is a series of spaced radially disposed substantially segment shaped openings 15 through which is adapted to flow water from the bath tub to the waste pipe.

Within the cap or shell 13 is a cut-off shutter 116 which is correspondingly shaped for limited rotation, the shutter being to the'said cap or shell and is held therein silientgasket or washer which serves towith a plurality of radially disposed segment shaped openings 18 which are adapted to register with the openings 15 in the cap or shell when the water is to be drained or let out of the tub. The non-perforate portion 19 between the openings-18 in the shutter 16 is adapted to close the openings 15 in the cap or shell 13 when the water within the tub is to be shut off from the waste pipe.

Beyond the outer end of one of the openings 15 in the cap or shell 13 is a SlqfiQO through which is projected a thumb-engiging gear 21 integrally formed with the .slfutter 16 so that the latter can be partly r0 tated for the opening or-ciosing of the waste port or opening in the tub, as Will-be clearly apparent. 4

Passed through' the apertures 14 and 17 in the shell13 and shutter '16, respectively, is the attaching member which comprises a screw 22 and a hook 23, the latter being formed with an internally threaded shank 24 for the adjustable engagement of the screw 22'therein, and this hook 23 engages the crossed arm spider D in the guard mounted in the waste opening or port and in this manner the stopper is fastened in place.

Surrounding the ring or collar 10 is a reefl'ect a fluid-tight joint between the stopper and the guard. I v

From the foregoing description, taken in connection with the accompanying drawlngs, the construction and manner of use of my invention will be readily apparent and, ti ,:efore, a more extended explanation has been omitted.

Having thus described my invention, I

Elalm:

respondingly shaped to the shell for opening and closing the same, said shutter rest-- ing upon the flange, a gasket concentrically of the ring and resting against the flange to form a fluid-tight joint between the entrance 'end of the waste pipe and said stopper a stem having a hook end and an opposite 1nternally threaded socket end, said hook end being detachably engaged with the guard, and a screw passed through the central opening in the shell and also centrally through the shutter and adjustably engaged in the internally threaded socket end of the stem,

said screwhaving its outer free end flush with the outer surface of the shell.

In testimony whereof I ailix my signature in presence of a witness GEORGE A. LUCKE.
